Oracle database licensing rules make licensing on VMware cost prohibitive. Instead Oracle prefers that you use their "enterprise" virtualization product, Oracle VM. Avoid it at all costs. Threaten to migrate to MS SQL... just don't use this thing. Pros: - Free - Relatively inexpensive suppo… more »
